Answer: Choice A) $\sqrt{34}$

Work Shown:

Use the distance formula

Points are (x1,y1) = (-4,3) and (x2,y2) = (-7,-2)

d = distance between the two points

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-4-(-7))^2 + (3-(-2))^2}\\\\d = \sqrt{(-4+7)^2 + (3+2)^2}\\\\d = \sqrt{(3)^2 + (5)^2}\\\\d = \sqrt{9 + 25}\\\\d = \sqrt{34}\\\\$

Extra info: $\sqrt{34} \approx 5.83$

If YW bisects XYZ and mZXYW = 25°, then what is mZXYZ?

Alisiya [41]

Answer:

50°

Step-by-step explanation:

Since, YW bisects angle XYZ.

$\therefore m\angle XYZ =2\times m\angle XYW\\\therefore m\angle XYZ =2\times 25\degree \\\huge \purple {\boxed {\therefore m\angle XYZ =50\degree}}$

0= 8-2x divided by 5

Stells [14]

Answer:

Step 1: Simplify both sides of the equation.

0= 8− $\frac{2x}{5}$

0 = 8 + $\frac{-2}{5}x$

0 = $\frac{-2}{5}x+8$

Step 2: Flip the equation.

$\frac{-2}{5} x + 8=0$

Step 3: Subtract 8 from both sides.

$\frac{-2}{5} x+8-8=0-8$

$\frac{-2}{5} x=-8$

Step 4: Multiply both sides by 5/(-2).

$(\frac{5}{-2} ) *( \frac{-2}{5} x) = (\frac{5}{-2} )*(-8)$

<h2>Therefor, the answer is x=20</h2><h2 />

* Hopefully this helps. Mark me the brainliest:)!!!

What is the value of x after these statements if the starting value of x is 3.

kolbaska11 [484]

[A]
$3^{2}=9$
$5^{3}=125$
$9\neq25$

Ignore

[B]
$3^{2} = 9$
$9 \ \textgreater \ 3$
Yes

$3^{3}=27$
$4( 3^{2})=36

27 \ \textless \ 36$
Yes

Therefore
$x=3+2=5$

[C]
$4^{5}=1024

 5^{4}=625

1024\ \textless \ 625$
No

$5^{5}=3125

 5^{5}=3125

3125\ \textgreater \ 3125$
No

Ignore

[D]
$5^{5}=3125

 2^{5}=32

3125\ \textgreater \ 32$
Yes

$5^{2}=25
25\ \textless \ 11$
No

Therefore
$x=5+8=13$

[E]
$8\ \textgreater \ 7$
Yes

Therefore
$x = 13^{2}=169$

I need help!!!<br><br> y=x-7<br> y=6<br><br><br> simplify the answer as much as possible

Alla [95]

Answer:

x=13 and y =6

Step-by-step explanation:

y=x-7

y=6

Substitute y=6 into the first equation

6 = x-7

Add 7 to each side

6+7= x-7+7

13 = x

x=13 and y =6

You take a three-question true or false quiz. You guess on all the questions. What is the probability that you will get a perfec

elena-14-01-66 [18.8K]

The probability that you will guess the first answer correctly = 1/2 = 0.5
The probability that you will guess the second answer correctly = 1/2 = 0.5
The probability that you will guess the third answer correctly = 1/2 = 0.5

The probability that you will guess all three answers correctly is

(0.5) x (0.5) x (0.5) = 0.125 = 12.5% .

============================

Here are all the ways your answer sheet could wind up:
(R = a right answer. W = a wrong answer.)

Number of possible ways to score 0 right out of 3 questions: 1 way
Number of possible ways to score 1 right out of 3 questions: 3 ways
Number of possible ways to score 2 right out of 3 questions: 3 ways
Number of possible ways to score 3 right out of 3 questions: 1 way

Statistically, if your answers are all pure guesses,
then on the average, the score you expect is

(0 + 33-1/3 + 33-1/3 + 33-1/3 + 66-2/3 + 66-2/3 + 66-2/3 + 100) / 8

= 400 / 8

= 50% .

If you're happy with that score, great !
Go to the movies the night before the test,
and start guessing.
